Let us first asume the simple case where the file is not a part
of any snapshot.
For a secure delete, a file needs to be overwritten in place and this
cannot be done on a FS that is always COW.
The secure deletion of the data would be something that hallens before
the file is actually unlinked (e.g. by rm). This secure deletion would
need open the file in a non COW mode.
